The only Uncle Tony video i watched was the one where he was talking about A.body rear ends. It surprised me because he is the only person I've ever heard saying anything positive about the 7 1/4" rear end. He called it a "downsized Dana60" and said "in a car less than 3300lbs and 300hp these things are "fantastic." All I can say is after my experience with one in a stock 273/904 car driven gently that sure wasn't true for me. I'm so glad I just decided to chase down a factory 8 3/4" rear. Now I won't have to worry about it again.
